JTokenAssertions.BeEquivalentTo should format the JSON document in a more readable fashion

[eerhardt]

Build 2 JObjects that are not DeepEquals. Call BeEquivalentTo on them and inspect the output message.

JObject result = ...;
JObject baseline = ...;

baseline
    .Should()
    .BeEquivalentTo(result);

Expected results

The message should be readable and easy to parse by a human. ex.

      Expected: {
        "runtimeTarget": {
          "name": ".NETCoreApp,Version=v1.0",
          "signature": "da39a3ee5e6b4b0d3255bfef95601890afd80709"
        },
        "compilationOptions": {},
        "targets": {
          ".NETCoreApp,Version=v1.0": {
            "dotnet.new/1.0.0": {
              "runtime": {
                "dotnet.new.dll": {}
              }
            }
          }
        },
        "libraries": {
          "DOTNET.new/1.0.0": {
            "type": "project",
            "serviceable": false,
            "sha512": ""
          }
        }
      }
      Result:   {
        "runtimeTarget": {
          "name": ".NETCoreApp,Version=v1.0",
          "signature": "da39a3ee5e6b4b0d3255bfef95601890afd80709"
        },
        "compilationOptions": {},
        "targets": {
          ".NETCoreApp,Version=v1.0": {
            "dotnet.new/1.0.0": {
              "runtime": {
                "dotnet.new.dll": {}
              }
            }
          }
        },
        "libraries": {
          "dotnet.new/1.0.0": {
            "type": "project",
            "serviceable": false,
            "sha512": ""
          }
        }
      }

Actual results

The output is pretty hard to decipher

      Expected JSON document {  "runtimeTarget": {    "name": ".NETCoreApp,Version=v1.0",    "signature": "da39a3ee5e6b4b0d3255bfef95601890afd80709"  },  "compilationOptions": {},  "targets": {    ".NETCoreApp,Version=v1.0": {      "dotnet.new/1.0.0": {        "runtime": {          "dotnet.new.dll": {}        }      }    }  },  "libraries": {    "DOTNET.new/1.0.0": {      "type": "project",      "serviceable": false,      "sha512": ""    }  }} to be equivalent to {  "runtimeTarget": {    "name": ".NETCoreApp,Version=v1.0",    "signature": "da39a3ee5e6b4b0d3255bfef95601890afd80709"  },  "compilationOptions": {},  "targets": {    ".NETCoreApp,Version=v1.0": {      "dotnet.new/1.0.0": {        "runtime": {          "dotnet.new.dll": {}        }      }    }  },  "libraries": {    "dotnet.new/1.0.0": {      "type": "project",      "serviceable": false,      "sha512": ""    }  }}, but differs at "libraries": {  "dotnet.new/1.0.0": {    "type": "project",    "serviceable": false,    "sha512": ""  },  "@@ Removed": [    "DOTNET.new/1.0.0"  ]}.

I think putting some newlines in here would make it much easier to read.
